In the old news department, there are good online discussions that debate tags versus labels without seeming to get to the point about Wordpress blog tags versus Blogger blog labels.
OK here goes - a Wordpress tag is a user keyword that spans all the wordpress blogs but a blogger label is a user keyword for an individual blog.
Not that complicated.
So for bold lentil if you click on one of my Wordpress posts, say Karl Attacks, with the tag 'stencil' you get this. Which is all the Wordpress blog posts with the tag 'stencil'.
On the other hand if you click on one of my Blogger posts, say Robin Gunningham stencil, with the label 'stencil' you get this. Which is all of Bold Lentil's Blogger posts with the label 'stencil'.
Pretty simple.
Now why cross-blog is another question but at a minimum it gives deeper appreciation to some differences between Wordpress and Blogger.
Maybe next week.
